alarm clock

Some models project the time onto a wall or ceiling, show calendar/date information, or include sleep‑trainer features such as colored nightlights, soothing sounds, and nap timers.

Child‑focused clocks combine sleep‑training lights and friendly faces with multiple nightlight colors, soothing sounds, nap timers, and visual wake indicators (for example, green “ok‑to‑wake” cues).

Common features include an alarm with a snooze function and adjustable snooze timers; several models list dual alarms. Child‑focused models may additionally offer a silent or audible nap timer.
